IMPROVEMENT IN SHUTTER? WORKERS AND F sTENEfis.

Specification forming part of Letters Patent no; name, dated February a, 1876; application filed December 27, 1875. 1

To all whom it may concern Be it known that I, JOHNiW. COOPER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Window Shutter Workers and Fasteners; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and usethe same, reference being bad to the accompanying drawing, and to the letters of reference marked thereon, which form apart of this specification.

My invention relates to improvements in devices for operating and fastening windowshutters; and consists in a novel combination and arrangement of parts," the natureof which will be hereinafter more fully explained and definitely claimed.

In the drawings, Figure 1 represents a top view of the nether plate; Fig. 2, an under side view of the upper plate; Fig. 3, a plan view of the device complete, and Figs. 4 and 5 detached views of the clip and latch.

In each of the views similar letters of reference are employed to indicate corresponding parts wherever they occur.

a and b are the upper and nether plates,

which form the turn-table, to which are secured, and by which the arms a a are held in proper position and operated to open and close the shutters S. The upper plate a is provided with the skirt or rim. 0;, which extends downward sufficiently to surround and inclose the nether plate b when placed over the latter. The plate a has a central circular projection, a and hole a. corresponding to the recess b and hole I) in the plate I), which, when the two plates a and b are placed in po- ,position and secured by a. screw or bolt through the holes a b will give strength and steadiness to the device. The slot a7, formed half round the plate, is adapted to admit of the passage of the shaft of a locking bolt or screw, 0, and the rotation of the plate about said shaft. 0 is a toothed rack formed on the plate a, and extending, by preference, half round the plate a, or so far as it is desired that the plate should rotate.

The plate I) is secured to the window-sill'by screws 12 11 b is a female screw, into which is turned the male screw or bolt c.- b is a toothed rack formed on the plate b adapted to correspond and engage with the rack a when the latter is pressed down against the plate b. b b are spiral springs so arranged that, when pressure is removed, they will lift the platen, and disengage the racks e and b In the drawings I have shown two springs. Any other suitable numbervmay be employed.

The operation of the device is as follows: When the device is desired to be locked, the screw c is turned down, so as to press the upper plate against the nether plate, and cause the rack e to engage with the rack b A reverse movement of the screw will release the plate, when the springs 12 b will push the plate aupward, thereby disengaging the racks, so that the arms a a? may be moved outward or in ward at pleasure. (I is the clip attached to the outer end of the arm a. It is connected to the arm a by, and turns freely on, the pin f, and is secured rigidly to the shutter. The clip a is also provided with a slot, 13, and recesses or bearings v1 as shown. It is a weighted latch working in the slot t, having journals 70 extending into the bearings i, and having formed on its end a hook, it, and on its upper side the lever-handle R The bearings t are so placed that when the clip is secured fast to the shutter the journals 10 will be held securely in place, and the latch it retained in the slot, with capability of being turned upward, the hook 70 extending below the clip,

so that it will readily slip over and lock on the ordinary catch on the window-sill, thereby holding the shutter closed without necessitating the turning of the screw 0. d is a'plate I and b and the springs b b simply relying on the friction of the adjacent parts for the holdring power.

The plate e may be formed reversible by forming the rim a so as to project equally over each side, and by forming duplicate parts 12 on either side.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The window-shutter worker, consisting of the plate a, supporting and carrying the arms a a and having the projections a and slot at", in combination with the plate b having the recess b, and a suitable holding device, all constructed, arranged, and operating substantially as and for the purpose specified.

2. The combination, with the plates at and b, of the racks e and b substantiallyas' and for the purposedescribeda 3. The combination, with the plates at and I), provided with racks e and b of the springs b substantially as set forth.

4. The combination, with a window shutterworker, of a combined clip and latch, consisting of the clip a slotted at i, and provided with bearings i, and a weighted latch, 70, working in the slot, the whole being constructed, combined, and operating substantially as shown and described,for the purpose set forth.

In testimony that I claim the foregoing as my own, I afiix my signature in presence of two witnesses.
